Abstract

Early fire detection is a critical requirement in indoor safety systems, where delays of only a few seconds can escalate into severe damage and casualties. Conventional devices often rely on single-sensor thresholds, which are highly susceptible to false alarms and unstable performance in dynamic indoor environments. This study develops an Internet of Things (IoT)-based multi-sensor fire detection and autonomous firefighting system integrated with a C4.5 decision tree classifier for real-time hazard recognition and short-term risk prediction. The prototype combines DHT22 temperature, MQ-135 gas, infrared flame, and ultrasonic water-level sensors with an ESP32 microcontroller, servo-controlled nozzle, and pump-based water spraying, all connected to an Android–Firebase platform for remote monitoring. A multivariate time-series dataset of 200 sensor sequences was preprocessed using a five-step sliding-window model and evaluated through 1,000 repeated hold-out trials. The C4.5 classifier achieved a mean accuracy of 84.9%, with peak values exceeding 90%, and clearly separated Safe, Alert, and Danger states, with smoke concentration emerging as the dominant predictor. Experimental tests in a 60 × 40 × 30 cm chamber produced 1–2 s reaction times, eight successful extinguishing events, and four failures attributable to mechanical belt detachment rather than model errors. These findings indicate that interpretable decision-tree models, when combined with IoT sensing and autonomous actuation, can provide a low-cost framework for real-time fire warning and automatic suppression. Future work should address mechanical robustness, extended deployment, and multi-room scalability

Abstract

Penelitian ini membahas tentang perancangan dan penerapan alat pengering terasi udang rebon otomatis berbasis mikrokontroler ESP32 dengan metode Research and Development (R&D). Tujuan utama dari penelitian ini adalah untuk meningkatkan efisiensi proses pengeringan dan menjaga higienitas produk yang selama ini masih dilakukan secara tradisional dan bergantung pada kondisi cuaca. Alat yang dikembangkan dilengkapi dengan sensor DHT22 untuk membaca suhu dan kelembaban, elemen pemanas 300W sebagai sumber panas, serta kipas DC 12V untuk menjaga sirkulasi udara di dalam box pengering. Sistem bekerja secara otomatis dengan mengatur pemanas dan kipas melalui relay berdasarkan data sensor, sehingga suhu dan kelembaban tetap stabil selama proses pengeringan. Hasil pengujian menunjukkan bahwa alat ini mampu mengurangi waktu pengeringan dari ±3–4 hari (metode tradisional) menjadi ±8 jam, dengan hasil yang lebih bersih dan konsisten. Penggunaan alat ini diharapkan dapat membantu pelaku UMKM dalam meningkatkan produktivitas dan kualitas produk terasi udang rebon secara efisien, higienis, dan berkelanjutan.
